Figure 3 Data management at a remote site
Managing data at a remote site allows you have a secondary volume in a storage system that is
physically different from the storage system where the primary volume resides. Application Agent uses
the Continuous Access Software or Continuous Access Journal copy type to back up or restore volumes
to or from a remote site.
In this manual, using the volume copy function along with the Continuous Access Software or Continuous
Access Journal copy type to copy a volume to a remote site is generically referred to as copying a
volume between storage system (or the remote copy function). By backing up data to a remote site,
you can restore the data from the remote site should a problem occur in the storage system at the
local site. This improves the stability of data. Backing up data on a remote site is a great way to
ensure a fast and easy recovery, if and when a disaster occurs, damaging the data on the local site.
Application Agent can perform the following operations on a remote site:
• Back up and restore data
• Re-synchronize a copy group
• Display resource information
• Lock a copy group
• Back up to and restore data from a tape device
• Mount or unmount a secondary volume
Managing generations
Application Agent can manage multiple secondary volumes for a single primary volume. In these
cases, the secondary volumes are referred to as generations (or generational backups).
